Abstract
The invention relates to a descaling formulation comprising cellulose microfibrils, in which at least 80% of the cells have primary walls and not more than 20% of the cells have secondary walls, with a degree of crystallinity of not more than 50%. The pH of the formulation is less than or equal to 1 and more particularly less than or equal to 0.5.
